Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a display device and particularly relates to a flexible display. [Prior Art] 近年来 In recent years, with the advancement of technology and the development of society, the use of display = product has become more and more extensive. And with the trend of electronic products = easy to carry, there is a more flexible display on the market. Referring to Figure 1, a schematic cross-sectional view of a conventional flexible display is shown. The flexible display 10 includes a flexible array substrate u, a display dielectric layer 12, a light transmissive substrate 14, and a driver IC (Driver IC) 15. The array substrate is constructed by a substrate 112 and a switching element array 114 disposed thereon. The display/enamel layer 12 and the driving wafer 15 are disposed on the array substrate, and the sheet 15 is electrically connected to the switching element array m. The light-transmissive substrate 13 is on the m2 4 dielectric layer 12, and the sealant 14 is formed on the array substrate 11, and the dielectric layer 12 and the light-guiding plate 13 are wound around, and the air or water rolling in the outside is damaged and damaged. The flexible display 10. After a plurality of flexings of the adjacent two-inch flexible display 10, the local crack of the sealant 14 causes the outside air or moisture to penetrate through the crack to damage the portable display 10. Therefore, how to avoid the occurrence of 4 slits for the phase to improve the package reliability of the flexible display 10 is actually the subject of the related art (4). SUMMARY OF THE INVENTION The outline of the invention provides a flexible display, and the frame-shaped display of the frame has good sealing performance after long-term use. - The present invention provides a flexible display comprising an array substrate, a display medium layer, a light transmissive substrate and a first sealant. The array substrate has a display area and a sealant coating area, wherein the sealant coating area surrounds the display area. The display medium layer is disposed on the array substrate and located in the display area. The light transmissive substrate is disposed above the display medium layer. The first sealant is disposed between the array substrate and the transparent substrate, and is located in the frame coating area to surround the display area. The first sealant has a first side wall and a second side wall, and at least one of the first side wall and the second side wall has a plurality of grooves, and the grooves are spaced apart from each other. Since the flexible display of the present invention has a plurality of spaced-apart grooves on the side wall of the sealant, when the flexible display is in a bent state, the grooves can relieve the stress on the frame knee to avoid the frame. The glue breaks due to prolonged or frequent bending, which in turn improves the packageability of the flexible display. The above and other objects, features, and advantages of the present invention will become more apparent and understood by the appended claims appended claims 2A is a schematic cross-sectional view of a flexible display according to an embodiment of the present invention, and FIG. 2B is a schematic perspective view of a flexible display according to an embodiment of the present invention. Referring to FIG. 2A and FIG. 2B, the flexible display 20 includes an array substrate 21, a display medium layer 22, a transparent substrate 23, and a first sealant 24. The array substrate has a display area 2102 and a sealant coating area 2104, and the sealant coating area 2104 surrounds the display area 2102. In detail, the array substrate 21 includes a substrate 212 and a switching element array 214 disposed thereon. The substrate 212 is a soft substrate, and the material may include plastics, such as polyethylene terephthalate (PET), polyethylene naphthalate 5 201033958 • (polyethylene naphthalene ' PEN), aromatic poly Aromatic • polyamide, Polyimide (PI), Polycycloolefin, Polysulfone (P〇lySulfone ' psu), Epoxy (Ep0Xy Resin), Polycarbonate (Polycarbonate, PC) ) or Polymethyl Methacrylate (PMMA). Moreover, the switching element array 214 can be an Active Matrix or a Passive Matrix. In the present embodiment, it is, for example, a Thin Film Transistor Matrix (TFT Matrix). The display medium layer 22 is disposed on the array substrate 21 and located in the display area 2102. The light-transmitting substrate 23 is disposed above the display medium layer 22 . Specifically, the display medium layer 22 may be an electro-phoretic layer, an electro-wetting layer, a liquid crystal layer, or an organic electro-luminescence layer. The light-transmitting substrate 23 may be a color filter substrate. The first frame adhesive 24 has a first sidewall 241 and a second sidewall 243, and is formed between the array substrate 21 and the transparent substrate 23 and located in the sealant coating region 2104. Moreover, at least one of the first side wall 241 and the second side wall 243 has a plurality of grooves 242. Specifically, the material of the first sealant 24 may include an ultraviolet curing hop or a heat hardening adhesive, such as Silica Gel, Polyurethane, Acrylic Resin, and Epoxy Resin. One of or a combination thereof. According to the above description, since the groove 242 does not penetrate the first side wall 241 and the second side wall 243' and the grooves 242 are spaced apart from each other, the outside air or moisture does not easily penetrate the first frame from the groove 242. The glue 24 causes damage to components inside the flexible display 20. That is to say, the first sealant 24 can not only effectively block the outside water vapor or air from penetrating into the flexible display 2〇, but can also reduce the number by using the groove 242 on the second side wall 243. A frame π above shows the stress experienced by 112() in the bent state to prevent the first-frame display 20 from being broken due to fatigue of the material strength after a plurality of bendings of the I-wound display 20.
特別的是，在本發明的其他實施例中，轉24可以包括 夕個框，單元24〇’且這些框膠單元：則系朝遠離顯示區· 向又錯層豐排列’如圖3所示。以本實施例來說，這些框 ，單兀240是在陣列基板21的框膠塗佈區21〇4内朝遠離顯示 區2012的方向排列成彼此交錯的兩層，而凹槽242在本實施 例中則相當於兩相鄰之框膠單元24〇之間的間隙。 值得一提的是，這些框膠單元240還可以其他方式排列， 且其形狀亦不限於圖3所示之四邊形。舉例來說，框膠240也 可以是呈多邊形，如圖4所示。特別的是，彼此層疊的框膠單 元240還可以具有相互配合的輪廓，以便於相嵌於彼此，如圖 5及圖6所示。 而且，這些框膠單元240除了可以藉由同一製程中形成在 陣列基板21與透光基板23間以外，也可以是獨立製成後再分 別配置於陣列基板21與透光基板23之間。本發明並未在此限 定框膠單元240的製程。 此外，在本發明的另一實施例中，第一框膠24中更可以 具有至少一開口 244，如圖7及圖8所示。開口 244係與凹槽 242交錯排列，以避免外界水氣或空氣直接經由凹槽242及開 口 244而滲入至可撓式顯示器20内部。本發明並未在此限定 第一框膠24中之開口 244的數量’且其亦可以是朝遠離顯示 區2102的方向交錯層疊排列，如圖9所示。 雖然在前述實施例中’第一框膠24的凹槽242與開口 244 7 201033958 均暴露出陣列基板21，但熟習此技藝者應該知道，即使在第 一框膠24的凹槽242或開口 244内配置有框膠層，只要其厚 度小於第一框膠24的厚度，其亦可達到減緩第一框膠24於可 撓顯示器20處於彎曲狀態下所受的應力。舉實施例來說，可In particular, in other embodiments of the present invention, the turn 24 may include a frame, the unit 24'' and the frame glue unit: the system is arranged away from the display area. . In the present embodiment, the frames , 240 are arranged in two layers staggered in the direction away from the display area 2012 in the sealant coating area 21〇4 of the array substrate 21, and the recess 242 is in the present embodiment. In the example, it is equivalent to the gap between two adjacent sealant units 24〇. It should be noted that the sealant units 240 may be arranged in other manners, and the shape thereof is not limited to the quadrilateral shown in FIG. For example, the sealant 240 can also be polygonal, as shown in FIG. In particular, the sealant units 240 laminated to one another may also have contours that cooperate with one another to facilitate embedding in each other, as shown in Figures 5 and 6. Further, the sealant unit 240 may be formed between the array substrate 21 and the transparent substrate 23 by the same process, or may be separately formed between the array substrate 21 and the transparent substrate 23. The process of the sealant unit 240 is not limited herein. In addition, in another embodiment of the present invention, the first sealant 24 may further have at least one opening 244, as shown in FIGS. 7 and 8. The openings 244 are staggered with the grooves 242 to prevent outside moisture or air from penetrating directly into the interior of the flexible display 20 via the grooves 242 and openings 244. The present invention does not limit the number of openings 244 in the first sealant 24 and may also be staggered in a direction away from the display region 2102, as shown in FIG.
